[PATCH v3] trailer: support multiline title

We currently ignore the first line passed to `git interpret-trailers`, when looking for the beginning of the trailers.

Unfortunately this does not work well when a commit is created with a line break in the title, using for example the following command:

git commit -m 'place of code: change we made'

That's why instead of ignoring only the first line, it is better to
ignore the first paragraph.
